DMRC Achieves Unprecedented Feat: Tunnels Under Live Rail, Flyover Without Disruption

• DMRC successfully dug a 6.35-meter tunnel 15 meters below an operational railway line, a flyover, and the Red Line Metro corridor.
• The tunneling work was completed without disrupting train, metro, or road traffic, a rare feat for the Delhi Metro.
• Advanced technologies and rigorous safety protocols were used to ensure the safety of train operations despite heavy trains passing overhead.
• The complex 203-meter tunneling section took 117 days due to approvals and challenging geological conditions.
• The project involves 11.4 km of TBM tunneling, six underground stations, and passes through densely populated areas with complex geology.
